Late playback in the strings section

Issue type

Muse Sounds bug

Bug description

This issue relates to playback issue 5 from the discussion here https://github.com/musescore/MuseScore/discussions/16674

Playback in the strings section blends notes together, plays late and occasionally loses notes.

Missing or blended notes are apparant when using shorter notes (semi, demi) quavers whilst late playback is even more apparant when using quavers when matched to the beat.

To visualise this, consider the following example for Violin with Woodblock keeping the beat. (The second woodblock was for me to line up the two staves in Ardour).

The last quaver in each bar appears almost a full quarter note late, but due to the faded entrance of the note, doesn't actually sound fully until the first beat of the next bar. This puts the strings a full half beat behind the rest of the orchestra as can be seen in the screenshot from Ardour

Additional context

No response

Reproduce the issue with the attached string bugs.mscz.zip file after renaming it to .mscz, using the Violin and Woodblock parts described in the report. Compare the strings' timing and note playback against the beat; done means short notes are not blended or lost and the strings no longer play late.
